What is a wind-girder?

Answer 1

The roof of a fixed roof tank assists in keeping the shell rigid and wind forces are transmitted to the bottom of the tank.

Open top or external floating roof tank do not have the benefit of this shell rigidity and therefore a circumferential wind girder is provided at or near the top of the shell to give it necessary stiffness. This girder is normally attached to the external surface of the shell and in many cases also used as an access and maintenance platform.
